I’ve noticed a few times that the Comodo icon goes missing from the notification tray, or in my case, from the hidden part of the tray. It is set for “Only show notifications” in the Customize section, but isn’t showing the icon at all at the moment. I can get the icon back by running cfp.exe direct from its folder, but it will go missing again whether it be today or next week. Because it seems random as to when it disappears, I have been unable to track down what might be the cause.
Considering icons have been mixed in the past, I would consider resetting the notification Area Icons Cache.
This can be done manually or by running the batch file in the link below.
Note: This does automatically delete 2 registry entries that are instantly recreated on system reboot. Notification Area Icons - Reset
Also in the bottom left corner of the customize notifications settings, select ‘Always show all icons and notifications on the taskbar’ then OK.
Sorry I somehow missed that it was missing from the hidden area and was thinking you wanted it visible at all times (Doh).
The setting above was to have it visible at all times, which could also be set individually to do so.
Please disregard the suggested setting in your case.
I hope resetting clears the issue for you.
